Banks has got the the intelligence, experience and skill to be successful through his music.

Haters choose to forget how Banks dominates the rap game, so he calls them out for having Alzheimer’s disease; a sickness that typically old people get when they age. It decreases the thinking and memory of the brain, basically referring to his haters as retards for ignoring him.
